INVENTOR ATTORNEY WITNESSr STATES PATE'I' POST.

T 0 all whom it may concern Be it known that I, JOHN WILLIAM STALDER, acitizen of the United States, residing at Lincoln, in the county ofLancaster and State of Nebraska, have invented new and usefulImprovements in Posts, of which the following is a specification.

This invention relates to posts or poles and has for an object theprovision of a reinforced concrete structure, which may be manufacturedeither asfa pole for the support of telegraph wires and the like, or apost for fences, buildings or other structures.

Another object of the invention is the provision of a structure as abovestated, which will accommodate various types of devices for connectionwith telegraph or fence wires and the like and in addition, provide forremovable and adjustable engagement with a support for the accommodationof persons working at any height upon the post or pole.

With the above and other objects in view, the invention further includesthe following novel features and details of construction, to behereinafter more fully described, illustrated in the accompanyingdrawings and pointed out in appended claims.

In the drawings Figure 1 is a front elevation of a post or poleconstructed in accordance with the invention, a telegraph cross armbeing shown in position at the top of the post or pole and in addition,a wire fastening device and a support are also shown applied. 7

Figure 2 is a fragmentary side view of the same.

Figure 3 is a top plan view.

Figure 4 is a front elevation of a fence post showing the manner ofsecuring the line wires thereto.

Figure 5 is a transverse sectional view of the same.

Figure 6 is a front elevation illustrating the manner of engagementbetween the supporting device and pole.

Figure 7 is a fragmentary perspective view of the post or pole.

Figure 8 is a detail perspective view of the fastening device shown inFigure 4:.

Figure 9 is a similar view of the supporting member.

indicates the post or pole Which is formed of concrete or othercementitious mixture. The post is provided along one face with a slot orgroove 11 and is reinforced by a metallic member which is preferablyformed from a single sheet of metal and shaped to provide asubstantially rectangular portion 12, from which extends a passageformed by spaced flanges 13. These flanges abut the walls of the slot 11so as to provide a lining for the said slot. Opposite the slot 11, thereinforcing member is formed with a substantially circular portion toprovide a passage 14, the latter being designed to accommodate electricwires when desired. The reinforcing member thus provides a wire passagewhich has a substantially T-shaped slot for the accommodation of variousdevices.

One of these devices consists of a cross arm 15, by means of whichtelegraph or other wires may be supported upon the pole, the said armbeing secured in position by a bolt whose head 16 is adjustablelongitudinally within the portion 12 ofthe the reinforcing member andwhose shank extends through the slot and through the arm 15 and receivesan. adjusting nut 17. In order to prevent pivotal movement of the arm,the latter has pivotally secured near each end a brace 18, one end ofwhich is pivotally secured to the arm and the opposite end provided witha right angular extension 19 for entrance within the slot 11.

As a means for securing a fence or other wires there is provided afastening device which includes a body portion having an opening 20therein for the passage of a bolt similar to the one previouslydescribed. the said body portion further including oppositely extendingarms 21 which are adapted to engage over a wire 22 so as to clamp thelatter to the face of the post. A lug 23 extends at right angles fromthe body portion of the fastening device and enters the slot 11 so as tohold the said device against pivotal movement. One of these devices maybe so adjusted upon the post as to provide a stop for preventinglongitudinal movement of the ends of the braces 18 within the slot.

For the purpose of providing a support for persons working at any heightalong the pole, there is provided an adjustable device which includeslaterally extending arms 24, from which extends a shank 25 which isadapted to enter the slot 11 and is provided with a transverse head 26which lies within the rectangular portion 12 of the reinforcing memberand permits of the outward pivotal movement of the support. The head 26may be inserted within the reinforcing member by disposin the said headlongitudinally within the slot 11 and giving the support a quarter turnso that the head will lie within the rectangular portion 12. To hold thesupport in position, there is provided an arm 27 which extends from thearms 21 in a di rection opposite to the shank 25, the said arm 27 beingprovided with an inwardly extended wedge-shaped member 28 which isadaptedto be wedged between the walls of the slot and to frictionallyhold the support in position. As the flanges 13 which form a lining forthe walls of the slot ll permit of a certain amount of give, thesupportmay be secured in position against accidental dis placement.

The invention is susceptible of various changes in its form, proportionsand minor details of construction and the right is herein reserved tomake such changes as properly fall within the scope 01" the appendedclaims.

Having described the invention what is claimed is 1- 1. A post formed ofcementitious material and provided with a groove extendinglongitudinally along one face thereof, an entrance passage extendingtherefrom, the walls of said passage lying within and forming the wallsof the longitudinally extending groove and a cable passage upon the sideof the rectangular portion opposite the groove, inwardly extendinglongitudinally disposed spaced ribs located at the intersection of therectangular portion and cable passage and providing restrictedcommunication there between and headed fastening devices engageable insaid groove.

2. A post formed of cementitious material and provided with a grooveextending longitudinally along one face thereof, a metallic reinforcingmember extending longitudi nally of the post, said member being formedof a single sheet of metal and shaped to provide a cross sectionalrectangular portion, an entrance passage extending therefrom, the wallsof said passage lying within and form ing the walls of thelongitudinally extending groove and a cable passage upon the oppositeside of the rectangular portion opposite the groove, inwardly extendinglongitudinally disposed spaced ribs located the intersection of therectangular portion and cable passage and providing restrictedcommunication th'erebetween and headed fastening devices engageable' insaid groove.

The combination with a post having a substantially T-shape'd grooveextending longitudinally therefrom, of a support cemprising a headedmember engageable within the groove, an arm extending therefrom throughsaid groove, supports extending from said arm and a wedge-shaped grooveengaging extremity formed on the arm In testimony whereof I afiix mysignatrlre.

JOHN WILLIAM STALDER.
